TSmuxer can slow down 25fps to 23.976, provided the source is progressive. It won't change the audio, so you will need to encode and sync properly timed audio separately.
Avidmux can slow down both video and audio, but audio this way is limited to AAC or AC3. Leaving audio direct in formats such as DTS or PCM will sound garbled.
